Need help figuring out an eve lander

[mattig89ch]

Hello all,

I wanted to land on eve, with a lander that could make it back into orbit in my career mode game.

trouble is, I can't figure out a lander to land at least one guy, and bring him back into orbit for pick up.

I know the general rule of thumb, that if your lander can get to a 150x150 orbit on 2/3 power on kerbin, you can do the same on full power on eve. But that doesn't help me if I can't get a lander to get up to a 150x150 orbit on kerbin.

does anyone have any tips? or anyone have any screen shots of landers they used for this?

A manned eve return mission is one of the hardest things to do in the game. You need about 12,000 m/s delta V to get to orbit from sea level, but only around 7,500 to make it from the tallest mountain. (For comparison, you need about 4,500 to get into orbit from kerbin.)

Basically, asparagus it all to hell, use aerospikes, and keep the payload as light as possible. One trick that many people use is instead of sending down a whole command pod, just send down a single kerbal on a chair, sitting on top of the smallest probe core. For my eve lander, the final stage was just the second smallest 1.25m tank and a rockomax 48-7s, with some batteries, a probe core, couple solar panels, and a kerbal. It was god for about 4,000 m/s.

That's what my lander looked like; managed to land it with completely full tanks at a good altitude.

And that's the last stage that I was talking about.

I found it easy to build a lander having 10k dV but adding last 2k is a challenge. Simple 8 symmetry asparagus will do with something like that on the top.

Traches lander should have somewhat 9k dV? So it should be capable of launching from EVE from anywhere above 4-5km altitude.

Currently I'm sending a rescue mission to the EVE. Lander has about 12k dV, will see how it goes.

If you are having trouble getting enough delta-V you should try to put everything that you don't need for the ascend on decouplers and drop it on lift off. Use girders as landing legs and stick all the parachutes, batteries and science stuff on them. A close-up of my lander:

And don't rely completely on large solar panels! The can break on Eve. I think my panels broke when I used time warp to walk my Kerbal to the lander. Put some drogue chutes on your lander if you can to minimize the stress. Eve's dense atmosphere will slow you down more than Kerbin's. Don't forget that your Kerbalnaut has mass in the command chair! Add 90kg (100 to be save) and make sure he doesn't throw your center of mass off.

Happy ascending and good luck!

Here's mine, 4 Kerbal capacity, lands hard, but intact. Gets all the kerbals back into orbit from sea level.
